Antioxidants (E-numbers)
Antioxidants (E300–E399, alongside acidity regulators) stop fats and oils going rancid and help protect colour. They include vitamin C (E300), tocopherols (E306–E309) and synthetic ones like BHA (E320) and BHT (E321).
37 additives in this class, grouped by regulatory level. Informational only — not medical or dietary advice; see the methodology.

Questions about antioxidants
- What are antioxidants?
- Antioxidants are food additives that act as antioxidant — used to stop fats and oils going rancid and to protect colour. In the EU they are identified by E-numbers and approved under Regulation (EC) No 1333/2008.
- Which E-numbers are antioxidants?
- Forkin tracks 37 antioxidants — for example Glucose oxidase (E1102), Calcium Disulphite (E225), Ascorbic Acid (Vitamin C) (E300), Sodium Ascorbate (E301). The full list with each one's regulatory level is on this page.
- Are antioxidants vegan?
- It depends on the individual additive and its source — many can be produced from plant, mineral or animal-derived raw materials, and the label rarely says which. The Forkin app shows verified vegan and vegetarian status per product.
